operating system
n. [techspeak] (Often abbreviated `OS') The foundation software of a machine; that which schedules tasks, allocates storage, and presents a default interface to the user between applications. The facilities an operating system provides and its general design philosophy exert an extremely strong influence on programming style and on the technical cultures that grow up around its host machines. Hacker folklore has been shaped primarily by the Unix , ITS , TOPS-10 , TOPS-20 /TWENEX , WAITS , CP/M , MS-DOS , and Multics operating systems (most importantly by ITS and Unix).

Operating system
The master control software system that serves as a foundation for applications software. Examples of past, present, and forthcoming operating systems include MS-DOS, Amiga DOS, Windows, Windows 2000, Windows Chicago, Windows Cairo, OS/2, Workplace OS, Apple/Mac Systems 7 and 8, Taligent (Pink), PowerOpen, NEXTStep, Rhapsody, Unix, SCO, AIX, HP/UX, HP/MPE, SCO Open Desktop, Solaris, and UnixWARE (Novell). A second class of operating systems is known as real time processing. These are used more for on-the-fly control systems such as aviation control systems and military applications. Examples include the Intel Multibus and iRMX operating systems. For a comparative analysis of the 32-bit options, see PC/Computing Special Report (1994) where it is concluded that there are advantages and drawbacks of each option and no clear optimal choice at this juncture in time. For 10 years, Apple Corporation would not license its proprietary Mac operating system to other manufacturers. However, in 1994 Apple announced that it would license its System 7 operating system to other vendors on PowerPC computers. In 1997, plans for Copeland and Gershwin upgrades were abandoned in favor or Rhapsody. Apple's hopes are riding heavily upon the evolution of a new operating system called Rhapsody that is a revolutinary operating system based upon NEXTStep technology. This may help to overcome the problem that Apple Corporation's market share has declined to less tan 5% of the desktop computing market and an even smaller percentage of the laptop/notebook computer market. The new licensing agreement is designed to cut into the huge market share of Windows operating systems from Microsoft Corporation. However, Microsoft Windows still remains the market share choice. Then along came Linux to challenge the Microsoft's operating systems. Linux (pronounced Leenicks) is a freely-distributable implementation of UNIX that runs on a number of hardware platforms, including Intel and Motorola microprocessors. It is very popular among computer scientists who have freely given their time to develpment of Linux. AThe Linux home page is at http://www.ssc.com/linux/ . (See also Cross-platform, Amiga, Windows, DOS, Windows Cairo, Windows Chicago, Windows 2000, Mac, Alpha processor, Mozart, Copeland, Gershwin, Native, OS/2, Wintel, and Rhapsody.)

Apple Corporation's operating system for its Mac OS X servers is called "Darwin." Apple announced that it will make the Darwin source code available to developers. It is a variant of UNIX.

Operating System
Also known as an "OS", this is the software that actually communicates with computer's hardware. Without an operating system, all software programs would be useless. The OS is what allocates memory, processes tasks, accesses disks and peripherials, and acts as the user interface. With an operating system, like the Mac OS or Windows 98, developers can write to a common set of programming interfaces (known as APIs) using the operating system to talk the hardware. Without an operating system, programmers would have to write about ten times as much code to get the same results. Of course, there are people who have to program the operating system itself...

operating system
An integrated collection of routines that service the sequencing and processing of programs by a computer. Note: An operating system may provide many services, such as resource allocation, scheduling, input/output control, and data management. Although operating systems are predominantly software, partial or complete hardware implementations may be made in the form of firmware. (188 )

Operating system
An operating system (OS) is the software that manages the sharing of the resources of a computer. An operating system processes system data and user input, and responds by allocating and managing tasks and internal system resources as a service to users and programs of the system. At the foundation of all system software, an operating system performs basic tasks such as controlling and allocating memory, prioritizing system requests, controlling input and output devices, facilitating networking and managing file systems. Most operating systems come with an application that provides a user interface for managing the operating system, such as a command line interpreter or graphical user interface. The operating system forms a platform for other system software and for application software. Linux and Mac OS (or any other BSD-derivative) are popular UNIX-like operating systems.
